Generally there are two basic kinds of SUVs, car-based and truck-based. Also known as crossover vehicles, car-based SUVs are built on unibody, use platforms and use a fully independent suspension and offer all-wheel drive. They typically provide better handling, ride comfort, and fuel economy than traditional, truck-based models and are generally rated higher overall in CR’s testing. They can be driven in moderate off-road situations, but they aren’t designed for more challenging off-road conditions, such as traversing high rocks or water, deep sand, or steep inclines or descents.
Traditional SUVs are built on body-on-frame platform (often the same platform used for a company’s comparable-sized pickup). They often offer greater towing capacity than a similar-sized car-based model, and when equipped with four-wheel drive, they are better equipped to tackle serious off-road terrain. But their handling can be cumbersome, and their ride can be harsh and jolting. Although most do not have independent rear suspensions, some newer body-on-frame SUVs are starting to offer it for more refined ride and handling.
For Consumer Reports’ testing purposes, we group SUVs according to size.

Well-suited for single people and families who are looking for more room than a sedan can provide, small SUVs offer flexible cargo space and a higher driving position than cars. Some small SUVs can have very good fuel economy that rivals some family sedans. Other small SUVs are thirstier for gas, have a rough ride, and poor fit and finish. For the more adventurous drivers, some models have off-road capabilities. If you are just looking for a vehicle that provides flexible cargo space, you might want to consider a wagon or hatchback because they provide better fuel economy and are more affordable. Some wagons are available with all-wheel drive and elevated ride heights.

The small, performance-oriented SUVs typically offer better acceleration and handling than regular Small SUVs, though fuel economy and price are common tradeoffs. In some cases, a model might have a version in each category, such as the Subaru Forester and Toyota RAV4. In those examples, the “sporty” models deliver significantly better performance. Often, the compact sporty SUVs are more upscale and come with luxurious interiors and more amenities.

Midsized SUVs have become alternatives to minivans and might satisfy the needs of many large SUV shoppers. Although many midsized
SUVs offer an optional third-row seat, they are often cramped and not easily accessible to adults. For many families, those
models provide a good balance of power, interior space, cargo space, and safety.

Most large SUVs are gas guzzlers and only get in the mid-teens for overall mileage. While they offer the most power, interior space, and towing capacity, they are typically not very agile and some can have clumsy handling. If you are looking to carry a lot of passengers, you may want to consider a minivan instead of a large SUV because they have better gas mileage, more comfortable passenger accommodations, and more flexible cargo space
